Betty White Gives Tips for a Long and Happy Life [VIDEO]

Are you looking to live a long and healthy life? If so, you might want to take some advice from Betty White, who, at age 89, is still going strong.

Last night, the Emmy-winning TV legend appeared on 'The Late Show With David Letterman,' during which she revealed her own tips on how to make it to your golden years.

Among the highlights: "Get at least eight hours of beauty sleep - nine, if you're ugly," "Try not to die" and "Never dwell on past mistakes - especially you, LeBron." (White was, of course, referring to Miami Heat star LeBron James, who this week lost the NBA Championship to the Dallas Mavericks.)
